At last, a playable version of 15 Puzzle! This is a Scratch version of the well-known sliding tile puzzle, designed to amuse and test your skill and intelligence. It looks simple, but to solve a test in a minimum number of moves, you must study the board configuration and devise a good tactic to put tiles in the order 1 to 15. A tile can be moved in 4 directions (up, down, left, right) towards the empty square. To move a tile, just click it. Dragging the slide control "difficulty" you choose the level of difficulty of the puzzles. The monitor "moves" accumulates the number of moves you made while solving a puzzle. To generate a new puzzle just click the "shuffle" button; the tiles will be scrambled, and you can begin solving the new puzzle. Enjoy!
